It is permanently installed. 3 is a box-shaped base member, and four support arms are integrally formed on the front side of the base member. This base member 3 has rows 25 disposed on its upper and lower surfaces, and the rows 25 are arranged on the upper and lower surfaces thereof.

It is assembled to be engaged with the lower guide rail 2 and movable along the guide rail 2vc across the width of the vehicle. The movement of the base member 3 is performed by a pinion 7 attached to the upper surface of the support arm 4 and rotated by a box motor 6, and a rack 8 provided on the upper surface of the upper guide rail 2 and meshing with the pinion 7. .

A bearing portion 9.10 is protruded from the tip of the support arm 4, and the finger part 11 is attached to this bearing portion 9.10. The finger bar 11 has a bearing part 1 on its back side.
2.13, these bearing portions 12.18' are placed on the bearing portions 9 and 10 of the support arm 4, and are connected by a shaft 14 so as to be freely rotatable in the horizontal direction. On the upper surface of the bearing part 12, there is a 7 flange 15 that slides into contact with the upper surface of the distal end of the support arm 4.
Of course, it is formed integrally, and three locating holes 16 are formed on the same circumference around the center of the shaft insertion part of the seven flange 16. 17 locating holes are formed, and how many of the locating holes 16 are aligned with the locating holes 17 with pins (not shown)? Drop in, is the first bolt not shown in the diagram? Screw in finger bar 1
1i Facing forward, or between the left and right sides, as in cents. For example, a pair of 7-inch 18i hooks are attached to this finger bar 11 as attachments.

According to such a conventional cargo handling device, cargo handling work 7 can be carried out in the manner shown in FIG. In other words, the one shown in Fig. 7 is for loading and unloading cargo on the left side of the vehicle, and the finger bar 11 is rotated and fixed to the left, the fork 18 is directed toward the left, and the motor 6 is driven forward and reverse to move the fork 18. (1m
When loading or unloading cargo that is advanced or retreated to the side, the finger bar 11.
Is fork 18 on the right side? The rest is the same as in case (A) above, except for the orientation.

(B) is the finger bar 11. When carrying out cargo handling work 2 in front of the vehicle with the 18 forks facing forward, the fork 18 can be moved left and right by the forward and reverse drive of the motor 6 to perform a function generally referred to as a side shift. .

However, with this conventional configuration, during the cargo handling operation shown in FIG. 2(B), the fork 18 protrudes far forward, resulting in an overhang from the front wheels of the vehicle! The problem was that t became very large, the center of load was far away from the vehicle body, stability deteriorated, and cargo handling capacity was reduced.

In view of these conventional problems, the present invention provides a cargo handling device that can minimize the amount of overhang of the attachment during front cargo handling with a simple configuration.
This is the purpose.

Said purpose? In order to achieve this, in the present invention, a support arm that supports the actuator is attached to a base member that is movable in the vehicle width direction along a guide rail on the front side of the carriage so as to be rotatable in the horizontal direction.

Hereinafter, the embodiments of the present invention will be described along with the drawings and the same reference numerals will be used for the same parts as the conventional structure. The details will be explained below.

In FIG. 8, a base m member 3A is movable in the vehicle width direction along the upper and lower guide rails 2 on the front side of the carriage l;
The support arms 4A supporting the attachment are formed separately from each other, and the front surface of the base member 3A and the support arms 4A are formed separately from each other.
Bearing portions 20.21 and 22.28 are integrally formed at the rear end of A. These bearing parts 20.21 and 22.2
Boss portions 20a and 21a are provided on the lower side of the 80 axis insertion portion, respectively.
22a and 28ai are integrally molded. Support arm 4
The outer diameter of the boss portions 22a and 29a on the A side is the same as that of the base member 8A.
The diameter is slightly smaller than the diameter of the shaft insertion hole of the side bearing portion 20.21. This support arm 4A has the boss portions 22a, 28
a' and is connected to the shaft insertion hole of the bearing portion 20.21 on the side of the base member 3A, and is assembled so as to be freely rotatable horizontally with respect to the base member 3A. Further, on the rear side of the upper bearing part 22 of the support arm 4A, a protrusion 24i is formed which slides into contact with the upper surface of the upper bearing part 20 on the base member side. Is there a shaft insertion hole on the upper surface of this bearing part 20? Three locating holes 26 on the same circumference as the center? 1. One locating hole 25 is also formed in the protruding piece 24, and this locating hole 25 is aligned with the tilt of the locating hole 26 to form a bottle (not shown). The support arm 4A can be pushed in or screwed into a bolt (not shown) to protrude forward, or can be folded parallel to the base member 3A.

The finger bar 11 is horizontally rotatably connected to the shaft 14 on the bearing parts 9 and 10 on the front side of the support arm 4A as in the conventional case, but in this embodiment, the finger bar 11 is connected to the shaft 14 on the bearing parts 9 and 10 on the front side of the support arm 4A. Recessed T at the end! 1527-1, protrusions 28 of approximately the same height are formed on both sides of the lower bearing part 130 on the finger bar 11 side interposed between these bearing parts 9 and 10 to fit into the recessed part. Yes, when the finger par 11 is set to the left or right, the protrusion 28 is in the recessed part 27.
It is designed so that it can just fit into the area and support it.

Furthermore, the base member 3A is moved in the vehicle width direction by a parallelogram link mechanism 29 and a hydraulic cylinder 30 instead of the conventional motor 6° pinion 7.2 shaft 8. The link mechanism 29 has one end connected to the guide rail 2-
A bracket 8 protruding from the upper side of the side plate 2a
-1, one side of the base member 3A is opened, the other end of the link mechanism 29 is passed through the base member 3A, and connected to a bracket 32 protruding from the circular surface of the side wall. The hydraulic cylinder 30 is rotatably attached to a bracket 33 protruding below the link support bracket 31, and the end of the operating rod 30a is connected to the intermediate connecting pins 2, 9 b of the side plate connecting side link 29a of the link mechanism 29. As the operating rod 30a of the hydraulic cylinder 30 moves forward and backward, the link mechanism 29 expands and contracts to move the base member 3A along the guide rail 2 in the vehicle width direction.

Next, the operation mode of the cargo handling apparatus having the structure of the above embodiment will be explained with reference to FIG. Figures 4 (AJ and 4B) show the case in which the finger pars 11 are rotated and fixed to the left and right sides, respectively, and used for lateral cargo handling by the fork 18, and the base member 8A is moved to the guide rail by the operation of the hydraulic cylinder 30. 2, move it in the vehicle width direction, and
8 to the side to perform lateral cargo handling.

At this time, by rotating and fixing the finger bar 11 laterally, the lower bearing portion 13 of the back surface of the finger bar 11
Since the protrusions 28 on both sides fit into the recessed part 27 at the front end of the support arm 4A, the support area of the finger par 11 becomes large, and therefore, the finger bar support rigidity increases.
When handling cargo with only one side of the fork 18, it is possible to prevent the finger par 11 from tilting and causing the cargo to collapse. (C) shows the case where the supporting arm 4A is folded to the right, and (C) shows the case where the supporting arm 4A is folded to the left. Even when this support arm 4A is folded, the protrusion 28 enters into the concave portion 27 of the support arm 4A as described above, increasing the finger bar support rigidity.

If the hydraulic cylinder 3o is actuated during this forward cargo handling, the base member 3A can be moved in the vehicle width direction to perform a side shift.

In addition, this forward cargo handling is carried out using the support arm 4 as shown in the same figure (g).
You can also do this with A stretched out. This is particularly useful when loading and unloading goods, for example, into the back of a truck bed. Here, a hydraulic cylinder 80. which moves the base member 3A. Since the link mechanism 29 is located between the upper and lower rails 2, it obstructs the operator's forward view.
It never happens.

In the embodiment shown in FIG. 6, the support arm 4A and the finger bar 11 can be automatically rotated. At each support shaft end of the support arm 4A and the finger bar 11,
For example, hydraulic rotary cylinders 84, 35 are assembled, and these hydraulic rotary cylinders 34, 85 and the base member 3A
By the operation of the hydraulic cylinder 30 that moves the Base member 3A
Cargo handling work can be carried out while moving in the width direction of the vehicle.
Work efficiency can be further improved.

It should be noted that although each of the above-mentioned embodiments discloses a fork as an attachment, it is needless to say that the attachment is not limited thereto.

In the embodiment shown in FIG. 6, the fork is attached directly to the support arm without using a finger bar.

Bearings 36 are fixed to the lower front and rear ends of the support arm 4A. Each of the forks 18A and 18B has two pawls 1.
8a and 18b are formed with a phase of 90 degrees,
- The ten-thousand fork 18A is fixed to the rotating shaft 37. The other fork 18B has a slide slit 39 in the vehicle width direction.
A projecting piece 38 having a diameter is integrally formed and is inserted through and disposed on the rotating shaft 37. The slide slit 39 engages with a key 40 fixed to an intermediate portion of the rotating shaft 37, and the fork 18 is fixed with a bolt 41 at the key 40 portion.
The distance between the forks 18A and 18B can be adjusted by moving the forks 18A and 18B closer to the vehicle body and moving them away or changing the position as appropriate. A handle 42 is attached to one end of the rotating shaft 37 with a bolt 43.
The claws 18a and 18b of each of the seven orcs 18A and 18B can be reversed laterally by operating the handle 42.

According to this embodiment, by rotating the rotating shaft 37 as shown in FIGS.
.

It depends on whether 18B is facing left or right. 7 Oak 18A, 18B load capacity is each fork 18A, 18B
The other claw portion 1sa or 18b of the support arm 4A is supported on the side surface. If the support arm 4A1 is folded as shown in FIG. 7 (IC), it can be used for forward cargo handling.

Here, if the rotary shaft 37 is made rotatable by a drive mechanism such as a hydraulic actuator, the tilting function that could not be performed during side cargo handling in the above-mentioned embodiment, that is, the fork 1
8A and 18B can be tilted rearward at an appropriate angle for cargo handling work.

As described above, according to the present invention, since the support arm is horizontally rotatable, the support arm can be folded parallel to the base member during forward cargo handling. By reducing the amount of hang, it improves stability and cargo handling capacity, as well as by reducing the minimum turning radius of the vehicle, making it easier to turn.
